Description

Technical Field

[0001] The utility model relates to the technical field of rubber ball cleaning, in particular to a rubber ball cleaning device for cleaning a condenser. Background Art

[0002] The condenser is a critical heat exchange device in a thermal power plant. Because circulating cooling water is not always clean, the inner walls of the condenser cooling water pipes can become dirty and scaled after a period of unit operation, impairing the condenser's heat transfer efficiency and increasing the end-over-heat ratio. A rubber ball cleaning device can remove or reduce scale within the cooling pipes without shutting down the unit, improving the cleanliness factor of the condenser cooling water pipes, reducing turbine exhaust pressure, and increasing unit output. The condenser rubber ball cleaning system consists of a ball collection net, a ball loading chamber, a ball pump, a manifold, valves, piping, and an electrical control cabinet. The quality of the ball collection net is directly related to the system's ball collection efficiency.

[0003] During use, existing ball collection nets experience significant water impact at the contact point between the net and the cylinder wall. This can create large gaps over time, easily trapping balls and resulting in a low ball collection rate, seriously impacting the safe and efficient operation of the generator set. Traditionally, the height of the ball collection net has been increased to reduce the net's grip on the balls, making them easier to release. However, this approach is inconvenient and costly to replace. Utility Model Content

[0028] Example 2:

[0029] See also Figure 1-4 The present invention provides a technical solution based on the first embodiment: the guide seat 1002 is arranged in a funnel shape, and the guide ball 1003 is arranged on the side of the guide seat 1002 with a smaller diameter.

[0037] Embodiment 5:

[0038] See also Figure 1-4The present invention provides a technical solution based on the first embodiment: arc-shaped guide plates are provided at the four corners of the water chamber 1 .

[0039] Analysis of the above content: The arc-shaped guide plate is set to prevent the circulating water from forming a vortex at this location. It also prevents the rubber balls from spinning on the spot when they reach this location and prevent them from entering the rubber ball recovery pipe.

[0040] Example 6:

[0041] See also Figure 1-4 The present invention provides a technical solution based on the first embodiment: a filter is installed in the air duct on the surface of the ball collector 3 and in the air duct on the top of the circulating water chamber.

[0042] Analysis of the above: Install a filter to prevent the balls from being expelled when draining the pipes. The balls should be regularly shaped (round) with uniform pore size. Before commissioning, soak them in water for seven days. After absorbing water, they should not deform or deteriorate, and the wet balls should not float on the water surface. The normal ball loading rate is 10% to 13% of the number of cooling tubes per side of the condenser. The lower or upper limit, or a value close to it, should be determined based on the time required for the balls to circulate once. Select quality balls. After soaking for a period of time, some balls may expand excessively, exceeding the diameter limit. These balls should be replaced promptly to prevent blockage of the cooling water pipes. Balls should also be replaced if they are severely worn or have lost their elasticity. Before each ball commissioning, air should be discharged from the condenser water chamber. When collecting the balls, increase the circulating water volume appropriately to ensure that the condenser circulating water inlet pressure is no less than 0.145 MPa.
